yellowblue To remove the child restraint, just unbuckle the vehicle's safety belt and let it go back all the way. The safety belt will move freely again and be ready to work for an adult or larger child passenger. If you were using a rear-facing child restraint, turn on the right front passenger's air bag when you remove the rear-facing child restraint from the vehicle unless the person who will be sitting there is a member of a passenger air bag risk group. See "AIR BAG OFF Switch" in the Index. CAUTION: If the right front passenger's air bag is turned off for a person who isn't in a risk group identified by the national government, that person won't have the extra protection of an air bag. In a crash, the air bag wouldn't be able to inflate and help protect the person sitting there. Your vehicle has an energy-absorbing safety belt for the right front passenger. This belt is designed to work with the air bag to provide restraint in some collisions by partially "giving" or yielding after first restraining the occupant's motion. In a crash, if the right front passenger's air bag is turned off, it wouldn't be able to inflate and help provide this restraint for the person sitting there. The larger the occupant, and the more severe the crash, the greater the risk becomes. Don't turn off the passenger's air bag unless the person sitting there is in a risk group identified by the national government. See "AIR BAG OFF Switch" in the Index for more on this, including important safety information. 1-48
